Description

本発明は、送風装置と、乗員を弾性的に支持可能なクッション材と、クッション材の流路部（送風装置のエアが通過可能な部位）を備えた車両用シートに関する。   The present invention relates to a vehicle seat including a blower, a cushion material that can elastically support an occupant, and a flow path portion of the cushion material (a portion through which air of the blower can pass).

この種の車両用シートとして、シートクッションと、シートバックを有する車両用シートが公知である（特許文献１を参照）。
シートクッションとシートバック（シート構成部材）は、各々、クッション材と、表皮材を有する。表皮材は、クッション材を被覆可能な袋状の部材であり、通気性を有する布材（布帛等）にて形成できる。
そしてクッション材は、シート外形をなす弾性部材（発泡樹脂製）であり、成形装置（第一型，第二型，キャビティ）にて成形できる。ここで第一型と第二型は互いに閉じ合せ可能な型部材である。またキャビティは、クッション材の形状に倣った空間部であり、第一型と第二型の間に形成される。
公知技術では、第一型と第二型の間（キャビティ内）に表皮材を配設したのち、キャビティ内で発泡樹脂材料を発泡させることにより、クッション材を成形しつつ表皮材に一体化する。このとき表皮材を真空吸引して第一型内面に押付ける（表皮材を密に圧縮する）ことで、発泡樹脂材料の含浸を極力防止できる。 As this type of vehicle seat, a vehicle seat having a seat cushion and a seat back is known (see Patent Document 1).
Each of the seat cushion and the seat back (seat constituent member) includes a cushion material and a skin material. The skin material is a bag-like member that can cover the cushion material, and can be formed of a breathable cloth material (cloth or the like).
The cushion material is an elastic member (made of foamed resin) that forms the outer shape of the seat, and can be molded by a molding device (first mold, second mold, cavity). Here, the first mold and the second mold are mold members that can be closed together. The cavity is a space that follows the shape of the cushion material, and is formed between the first mold and the second mold.
In the known technique, a skin material is disposed between the first mold and the second mold (in the cavity), and then the foamed resin material is foamed in the cavity, so that the cushion material is molded and integrated with the skin material. . At this time, the impregnation of the foamed resin material can be prevented as much as possible by vacuum-sucking the skin material and pressing it against the inner surface of the first mold (compactly compressing the skin material).

ところで上述の車両用シートでは、シート構成部材に送風装置を取付けて、乗員に向かって送風することができる。
このときクッション材に、流路部（クッション材を厚み方向に貫通する部位）を設けて、送風装置のエアを通過可能とする。そして送風装置を、クッション材の裏面側に配設しつつ流路部に連通することで、送風装置から吹出されるエアを、クッション材の流路部を通じて表皮材側（乗員）に送風できる。 By the way, in the above-mentioned vehicle seat, a blower can be attached to the seat constituent member to blow air toward the passenger.
At this time, the cushion member is provided with a flow path portion (a portion penetrating the cushion member in the thickness direction) so that the air of the blower can pass therethrough. And the air blown from the blower device can be blown to the skin material side (occupant) through the flow passage portion of the cushion material by arranging the blower device on the back surface side of the cushion material and communicating with the flow passage portion.

ここで流路部は、上述の成形装置を用いて、クッション材の成形と同時に形成できる（図８を参照）。
例えば第二型内面に突出部位６４ａ（流路部の外形に倣った部位）を形成する。つぎに第一型と第二型を閉合わせることで、突出部位６４ａを、第一型内面に向けて突出させつつ表皮材Ｓａに押し当てる。この状態で発泡樹脂材料を発泡させることにより、突出部位６４ａによって流路部２０ａ（空間部）を形成しつつクッション材Ｐａを成形できる。 Here, the flow path portion can be formed simultaneously with the molding of the cushion material using the above-described molding apparatus (see FIG. 8).
For example, a protruding portion 64a (a portion following the outer shape of the flow path) is formed on the inner surface of the second mold. Next, by closing the first mold and the second mold, the projecting portion 64a is pressed against the skin material Sa while projecting toward the inner surface of the first mold. By foaming the foamed resin material in this state, the cushion material Pa can be formed while the flow path portion 20a (space portion) is formed by the protruding portion 64a.

特開２００８−１４２２４４号公報JP 2008-142244 A

ところで上記構成では、突出部位６４ａが表皮材Ｓａを過度に押圧するなどして、表皮材Ｓａ一部が第一型に向けて凹み変形することがあった（図８（ａ）の丸で囲った部分を参照）。
そして表皮材Ｓａの凹み個所と突出部位６４ａの間（略三角状）に発泡樹脂材料が入り込む。これによりクッション材Ｐａ一部が表皮材Ｓａ側に突出して成形される（トゲ状の凸部位Ｐｘが形成される）ことがあった。
このため上記構成では、クッション材Ｐａに凸部位Ｐｘ（異物感の原因となる部位）が形成されるとともに、凸部位Ｐｘにより表皮材Ｓａが浮き上がることがあった（シート性能にやや劣る構成であった）。
本発明は上述の点に鑑みて創案されたものであり、本発明が解決しようとする課題は、流路部を備えたクッション材と表皮材を性能良く一体化することにある。 By the way, in the above configuration, a part of the skin material Sa may be dented and deformed toward the first mold because the protruding portion 64a excessively presses the skin material Sa (encircled by a circle in FIG. 8A). See below).
Then, the foamed resin material enters between the recessed portion of the skin material Sa and the protruding portion 64a (substantially triangular). As a result, a part of the cushion material Pa is sometimes protruded and formed on the skin material Sa side (a thorn-shaped convex portion Px is formed).
For this reason, in the above configuration, the convex part Px (part that causes a foreign body sensation) is formed in the cushion material Pa, and the skin material Sa may be lifted by the convex part Px (the configuration is slightly inferior to the seat performance). )
The present invention has been devised in view of the above points, and the problem to be solved by the present invention is to integrate the cushion material provided with the flow path portion and the skin material with good performance.

上記課題を解決するための手段として、第１発明の車両用シートは、シートクッションやシートバックなどのシート構成部材と、シート構成部材に配設の送風装置を有する。
シート構成部材は、シート外形をなす発泡樹脂製のクッション材と、送風装置のエアが通過可能なクッション材の流路部と、クッション材を被覆可能な表皮材を有し、送風装置から吹出されるエアを、流路部を介して表皮材側に送風可能である。
そして本発明では、上述のクッション材を成形装置のキャビティ内で成形するとともに、流路部を、キャビティ内に配設される突出部位にて形成する。この種の構成では、流路部を備えたクッション材と表皮材を性能良く一体化できることが望ましい。 As means for solving the above-mentioned problems, the vehicle seat of the first invention has a seat constituent member such as a seat cushion or a seat back, and a blower arranged on the seat constituent member.
The seat component member has a cushion material made of foamed resin that forms the outer shape of the seat, a flow path portion of the cushion material through which air of the blower can pass, and a skin material that can cover the cushion material, and is blown from the blower. The air can be blown to the skin material side through the flow path portion.
In the present invention, the above-mentioned cushion material is molded in the cavity of the molding apparatus, and the flow path portion is formed at the protruding portion disposed in the cavity. In this type of configuration, it is desirable that the cushion material provided with the flow path portion and the skin material can be integrated with high performance.

そこで本発明では、上述の表皮材が、シート構成部材の着座側に配置されて通気性を有する第一部位と、第一部位に積層されて発泡樹脂材料の侵入を阻止する第二部位と、第二部位に設けられてエアの通過可能な通過部位を有する。このように第二部位により発泡樹脂材料の侵入を極力阻止することで、表皮材本来の性質（柔軟性等）を極力維持しつつ、クッション材と表皮材を一体化できる。
そして本発明では、キャビティ内に表皮材を配置しつつ、突出部位を通過部位に対面配置するとともに、表皮材よりも剛性に劣る介装部材を、通過部位と突出部位の間に介装した状態でクッション材を成形する構成とした。
本発明によると、介装部材によって、表皮材の凹み変形を抑えつつ（性能向上を図りつつ）、クッション材に一体化することができる。 Therefore, in the present invention, the above-described skin material is disposed on the seating side of the seat constituent member and has a first portion having air permeability, and a second portion laminated on the first portion to prevent the intrusion of the foamed resin material, It has a passage part provided in the second part and through which air can pass. In this way, by preventing the intrusion of the foamed resin material by the second part as much as possible, the cushion material and the skin material can be integrated while maintaining the original properties (flexibility, etc.) of the skin material as much as possible.
And in the present invention, while the skin material is disposed in the cavity, the protruding portion is disposed facing the passage portion, and the interposed member that is less rigid than the skin material is interposed between the passage portion and the protruding portion. The cushioning material was molded.
According to the present invention, the intervention member can be integrated with the cushion material while suppressing the dent deformation of the skin material (while improving the performance).

第２発明の車両用シートは、第１発明の車両用シートであって、上述の介装部材が、通過部位に対面可能な対面部位を有する。そこで本発明では、対面部位の剛性を、対面部位を除く介装部材の他部位よりも低く設定したことにより、表皮材の凹み変形をより確実に抑えることができる。   The vehicle seat of the second invention is the vehicle seat of the first invention, and the above-described intervention member has a facing part that can face the passing part. Therefore, in the present invention, the dent deformation of the skin material can be more reliably suppressed by setting the rigidity of the facing part lower than that of the other part of the interposed member excluding the facing part.

第３発明の車両用シートは、第２発明の車両用シートであって、上述の対面部位を、通過部位よりも大きくした。これにより対面部位にて通過部位を確実に被覆するなどして、発泡樹脂材料の通過部位からの漏れ出し（表皮材の性能悪化等）を極力阻止することができる。   The vehicle seat of the third invention is the vehicle seat of the second invention, wherein the facing part is made larger than the passing part. This makes it possible to prevent leakage of the foamed resin material from the passage portion (deterioration of the performance of the skin material, etc.) as much as possible by covering the passage portion with the facing portion.

本発明に係る第１発明によれば、流路部を備えたクッション材と表皮材を性能良く一体化することができる。また第２発明によれば、流路部を備えたクッション材と表皮材を更に性能良く一体化することができる。また第３発明によれば、流路部を備えたクッション材と表皮材を、より確実に性能良く一体化することができる。   According to the first aspect of the present invention, the cushion material provided with the flow path portion and the skin material can be integrated with good performance. According to the second invention, the cushion material provided with the flow path portion and the skin material can be further integrated with high performance. According to the third invention, the cushion material provided with the flow path portion and the skin material can be more reliably integrated with good performance.

（介装部材の介装作業）
本実施例では、第二可動型５２ｂを型閉じして、突出部位６４を通過部位３４に当接させることにより、発泡樹脂材料の通過部位３４からの漏出しを防止する（図４及び図７を参照）。
そしてこのとき突出部位６４が表皮材６Ｓを過度に押圧するなどして、表皮材６Ｓ一部が第一型５１（着座側）に向けて凹み変形することが懸念される。
そこで本実施例では、表皮材６Ｓよりも剛性に劣る介装部材４０を、通過部位３４と突出部位６４の間に介装する（図６及び図７を参照）。このとき対面部位４２（より低剛性な部位）を通過部位３４に対面配置（被覆）する。

In the present embodiment, the second movable mold 52b is closed and the protruding portion 64 is brought into contact with the passage portion 34 to prevent leakage of the foamed resin material from the passage portion 34 (FIGS. 4 and 7). See).
At this time, there is a concern that the protruding portion 64 excessively presses the skin material 6S, and a part of the skin material 6S is recessed and deformed toward the first mold 51 (sitting side).
Therefore, in the present embodiment, the interposition member 40 which is inferior in rigidity to the skin material 6S is interposed between the passage portion 34 and the protruding portion 64 (see FIGS. 6 and 7). At this time, the facing part 42 (part having lower rigidity) is arranged (covered) facing the passing part 34.
By doing so, it is possible to suppress the dent deformation of the skin material 6S, for example, by absorbing the pressing force of the protruding portion 64 by the interposed member 40 (low rigidity member). At this time, since the facing portion 42 (lower rigidity portion) is disposed facing the passage portion 34, the dent deformation of the skin material 6S can be more reliably suppressed. By setting the diameter L3 of the facing portion 42 to be larger than the passage portion 34, leakage of the foamed resin material can be suitably prevented.

そして発泡樹脂材料を第二型５２からキャビティ５４内に射出したのち、発泡樹脂材料を発泡させる。そして発泡樹脂材料が硬化することにより、クッション材６Ｐを成形しつつ、クッション材６Ｐの表面に表皮材６Ｓを一体的に取付けることができる。
このとき第二部位３２にて発泡樹脂材料の侵入を極力阻止することで、表皮材６Ｓ本来の性質を極力維持しつつ、クッション材６Ｐと表皮材６Ｓを好適に一体化できる。
またクッション材６Ｐの成形と同時に、第二型５２（突出部位６４）にて、クッション材６Ｐに流路部２０を形成できる。
そして本実施例では、クッション材６Ｐと表皮材６Ｓの間に介装部材４０が介装された状態で、クッション材６Ｐと表皮材６Ｓが一体化されることとなる（図３を参照）。 Then, after the foamed resin material is injected into the cavity 54 from the second mold 52, the foamed resin material is foamed. When the foamed resin material is cured, the skin material 6S can be integrally attached to the surface of the cushion material 6P while molding the cushion material 6P.
At this time, the cushioning material 6P and the skin material 6S can be suitably integrated while maintaining the original properties of the skin material 6S as much as possible by preventing the penetration of the foamed resin material as much as possible at the second portion 32.
Simultaneously with the formation of the cushion material 6P, the flow path portion 20 can be formed in the cushion material 6P by the second mold 52 (projecting portion 64).
In this embodiment, the cushion material 6P and the skin material 6S are integrated in a state where the interposed member 40 is interposed between the cushion material 6P and the skin material 6S (see FIG. 3).

［送風装置の配設作業］
図２を参照して、送風装置１０をクッション材６Ｐ内（収納部）に配置しつつ、フレーム部材６Ｆに固定する。
そして送風装置１０を、ダクト部材２８を介して流路部２０に接続することにより、送風装置１０を流路部２０に連通できる。このように流路部２０を送風装置１０に連通することで、送風装置１０から吹出されるエアを、流路部２０を介して乗員に送風することができる。
本実施例では、送風装置１０から吹出されるエアが、流路部２０から介装部材４０（通気孔４４）を通過して、表皮材６Ｓ（通過部位３４）に導かれることとなる。 [Installation work of blower]
With reference to FIG. 2, the air blower 10 is fixed to the frame member 6 </ b> F while being arranged in the cushion material 6 </ b> P (storage portion).
And the air blower 10 can be connected to the flow path part 20 by connecting the air blower 10 to the flow path part 20 via the duct member 28. Thus, the air blown from the blower device 10 can be blown to the occupant through the flow passage unit 20 by communicating the flow passage unit 20 with the blower device 10.
In the present embodiment, the air blown from the blower 10 passes through the interposition member 40 (vent hole 44) from the flow path portion 20 and is guided to the skin material 6S (passage portion 34).

以上説明したとおり本実施例では、表皮材６Ｓよりも剛性に劣る介装部材４０を、通過部位３４と突出部位６４の間に介装した状態でクッション材６Ｐを成形する。このため介装部材４０によって、表皮材６Ｓの凹み変形を抑えつつ（性能向上を図りつつ）、流路部２０を備えたクッション材６Ｐに一体化することができる。
また本実施例では、介装部材４０が、通過部位３４に対面可能な対面部位４２を有する。そして対面部位４２の剛性を比較的低く設定することで、表皮材６Ｓの凹み変形をより確実に抑えることができる。
そして本実施例では、対面部位４２の径寸法Ｌ３を通過部位３４よりも大きめに設定する（より確実に被覆可能とする）ことで、発泡樹脂材料の漏れ出しを好適に阻止する。これにより表皮材６Ｓの部分的な硬化（発泡樹脂材料の漏れ出しが原因）などを阻止することで、表皮材６Ｓの性能を好適に維持できる。
このため本実施例によれば、流路部２０を備えたクッション材６Ｐと表皮材６Ｓを性能良く一体化することができる。 As described above, in the present embodiment, the cushion material 6P is molded in a state where the interposed member 40, which is less rigid than the skin material 6S, is interposed between the passage portion 34 and the protruding portion 64. For this reason, the interposing member 40 can be integrated with the cushion material 6P including the flow path portion 20 while suppressing the dent deformation of the skin material 6S (while improving the performance).
In the present embodiment, the intervention member 40 has a facing part 42 that can face the passing part 34. And the dent deformation | transformation of the skin material 6S can be suppressed more reliably by setting the rigidity of the facing part 42 comparatively low.
In this embodiment, the diameter L3 of the facing portion 42 is set to be larger than the passage portion 34 (so that it can be more reliably covered), thereby suitably preventing leakage of the foamed resin material. Accordingly, the performance of the skin material 6S can be suitably maintained by preventing partial curing of the skin material 6S (caused by leakage of the foamed resin material).
For this reason, according to the present Example, the cushion material 6P provided with the flow path part 20 and the skin material 6S can be integrated with good performance.
